ATENT APPARATUS FOR FASTENING BED-SPRINGS TO WIRE BASES.

SPECIFICATION forming part of Letters Patent No. 792,585, dated June 20, 1905.

Application filed November 11, 1904:. Serial No. 232,370.

To (0 11/71/0717 it may concern:

Be it known that we, JONAS F. DIXON and THOMAS J. RiDowAY, citizens of the United States, residing at Carthage, in the county of Jasper and State of Missouri, have invented a new and useful Apparatus for Fastening Bed- Springs to \Vire Bases, of which the following is a specification.

This invention relates to the art of attaching bed-springs to wire bases, and has for its object to provide improved means for bending the wires of the base at their points of crossing so as to snugly grip the lowermost coils of the bed-springs, and thereby prevent lateral displacement of the latter.

Another object is to arrange the anvil member of the apparatus for conveniently receiving a bed-spring and supporting the same in such a manner as to facilitate the threading of the wires of the base structure through the spring and to maintain the spring and the base in proper mutual relation when subjected to pressure to clamp the wires of the base upon the base-coil of the spring.

Another object of the invention is to effect convenient adjustment of a plurality of anvil members so as to readily set the same to the positions desired for the crossing of the basewires and the attachment of the springs.

Another object of the invention is to embody the punch member in form for convenient manipulation and to guide the same upon an anvil to the wires, so as to insure an effective bending and clamping of the same upon the springs.

\Vith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanyingdrawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a plan view showing a portion of two rows of bed-springs supported upon the device of the present invention with the crossed wires of the base structure threaded through the springs in readiness to be clamped thereon. Fig. 2 is a detail perspective view of the punch member of the present invention. Fig. 3 is a detail top plan view of the central portion of the anvil. Fig. 4 is a detail perspective view of the anvil member. Fig. 5 is an enlarged detail sectional view taken through the anvil with a bed-spring and a pair of crossed wires of the base structure supported thereon preparatory to bending the same. Fig. 6 is a similar view taken at right angles to Fig. 5. Fig. 7 is a view similar to Fig. 5, including the punch member and showing the wire after being clamped upon the spring. Fig. 8 is a view at right angles to Fig. 7. Fig. 9 is a detail perspective view of a bedspring and a pair of adjacent crossed basewires after being clamped upon the spring.

Like characters of reference designate corresponding parts in each and every figure of the drawings.

The present apparatus includes an anvil having a base 1, which is longer in one direction than the other and is preferably substantially elliptical in shape, with an integral clovetailed rib 2 extending longitudinally thereof upon its under side. An upwardly-tapered horn 3 rises centrally from the top of the base and is divided by bifurcations L and 5, intersecting at substantially right angles into four horn members 6, 7, 8, and 9, of which the horn members 6 and 7 are about one-third the height of the horn members 8 and 9. The horn members 6, 7, and 9 have rounded or convexed outer faces, while the outer face of the horn member 8 is flat, as indicated at 10. At opposite ends of the base are shoulders 11 and 12 in alinement with the bifurcation 5, while other shoulders 13 and 14: are at opposite sides of the base in alinement with the bifurcation. At diametrically opposite points upwardly-bowed springs 15 are provided upon the top of the base, with their outer ends suitably secured thereto and their inner upwardl yextending free ends lying adjacent the central post for the purpose of yieldably supporting the bed-springs, as will be hereinafter explained.

- For cooperation with the anvil there is a punch niember consisting of a shank or stock 16, terminating at its lower end in four radial wings 17, 18, 19, and 20, arranged to enter the bifurcations of the post or the anvil. A yoke-shaped holder 21 has its back carried by the stock or shank of the punch, so as to straddle the lower portion thereof, with its opposite ends in substantial alinement with the bottoms of the radial wings.

In using the present device a plurality of anvils are selected in accordance with the number of bed-springs to be employed in the bedbottom, and these anvils are placed upon substantially parallel supporting-bars 22, as indicated in Fig. 1, each of said bars being provided with a longitudinal dovetailed groove 23, intersecting at least one end thereof, into which the dovetailed ribs 2 of the anvil are introduced and the several anvils set at the proper intervals for the crossings of the wires of the base structure. After the anvils have been set in place a helical bed-spring 24: is placed upon each anvil, so as to embrace the horn thereof, with its base coil or ring 25 in an elevated position upon the free inner ends of the springs 15.

Ordinarily wire base structures for the support of bed-springs include spring-wires running in one direction and soft or pliable wires running in the opposite direction, wherefore when the bed-springs are clamped upon the wires of the base structure the base ring or coil of the bed-springs is bent and slightly displaced, and the spring does not always assume the desired upright position, thereby resulting in an inferior spring bed-bottom by reason of all or a large proportion of the individ ual bed-springs having slightly-different inclinations. To overcome this objection, it is proposed to have the base structure made up entirely of soft or pliable wires and to set or depress the base ring or coil of the bedspring upon said wires without displacing or affecting the said base-coil in order that the entire bed-spring may assume the desired upright position. in order to obtain this feature, the lower or base coil or ring 25 of the bed-spring has its greater portion disposed substantially in a horizontal plane, with the lower free extremity of the spring hooked over the initial partot' the coil, as at 26, whereby said coil is tight or rigid and cannot yield.

\V hen the coil has been seated upon the anvil, as in Figs. 5 and 6, a base-wire 27 is passed laterally in the direction indicated by the arrow in Fig. 6 between the two lowermost coils of the bed-spring and over the tops of the short horn members 6 and 7 until said wire rests in the bifurcation 5 and across the top of the base-coil 25. Prior to applying the wire 27 to the anvil a succession of depressions or kinks, one of which has been indicated at 27, are formed in the wire and spaced according to the positions of the bed-springs, whereby each kink or depression lies within the guideway 5 of the anvil. After the wire 27 has been fitted in place a cross-wire 28 is passed beneath the adjacent side of the base-coil 25, over the depression of the wire 27, and thence beneath the opposite sides of the coil 25. As the base-wires are soft or pliable, they may be readily bent to form the depressions 27, and the wires 28 may be threaded straight through the springs without bending, thereby facilitating the assemblage of the springs and wires. It will be understood that the bed-springs and the base-wires are supported in an elevated position above the base of the anvil by means of the springs 15 and are thereby out of contact with the base of the anvil. hen all of the base-wires have been fitted in place, the punch 16 is successively applied to the anvils for the purpose of bending the base-wires, and thereby connecting the springs thereto. \Vhen the punch has its wings fitted in the bifurcations of the post, the wings 17 and 19 lit in the bifurcation 5 and rest upon the basewire 27 directly above the base-coil of the spring, as indicated in Fig. 7 of the drawings, while the wings 18 and 20 enter the bifurcation at and bear upon the top of the basecoil 25 where it crosses the base-wire 28. The upper end of the punch is then repeatedly struck by a hammer or other suitable implement, whereby the blades 18 and 20 sink the basecoil 25 of the spring into the cross-wire 28, as shown in Fig. 8, the shoulders 13 and Hsupporting the wire 28 eXteriorly of the ring 25, so as to permit of the downward bending or depressing of that portion of the wire which lies between the shoulders, whereby the depressed portion of the wire constitutes a seat in which the base-coil of the spring is snugly gripped at the bends of the wire. The other wings 17 and 19 of the punch, as shown in Fig. 7, cooperate to aid in the depression of the base-ring by engaging the wire 27 at points directly above the ring, while at the same time the depression 27 of the wire 27 comes in contact with the base of the anvil, and thereby slightly reduces the depth of the depression 27 and kinks or bends upward that portion ot the wire 28 which lies within the base-coil of the spring until it comes in contact with the intermediate portion of the punch .16, whereby in addition to being seated in the depression or seat formed in the wire 28 the base-ring of the spring is clamped between the wires 27 and 28, the wire 28 passing beneath the coil and above the wire 27, while the wire 27 passes across the top of the coil beneath the wire 28. By reason of the fact that the wires 27 and 28 are soft or pliable whatever bending takes place is in said wires and not in the stitf elastic base-coil of the spring, whereby said horizontal base-coil is unatlfected, and thereby supports the bed-spring in its proper upright position. During the operation of the punch the shoulders 13 and let support the wire 28 external of the base-coil 25 and the ends of the yoke 21 lie above the wire 28 and at the outer sides of the shoulders 13 and 14:, thereby to prevent the wire from rising at these points under the influence of the downward bending of the wire between the two shoulders. After the completion of the operation of the punch the base-wires appear as shown in Fig. 9, from which it will be understood how the base-coil of the bed-spring is snugly gripped between the base-wires and is held against slidable movements thereon.

The purpose of giving the horn member 8 a fiat outer face 10 is to accommodate the lower end portion of the bed-spring where it is hooked over the base-coil, as such portion of the spring naturally assumes a straight disposition, and therefore it becomes necessary to slightly reduce the outer face of one of the long horn members to accommodate said portion of the spring.

After the punch has been successively operated upon all of the springs the bed-bottom may be lifted from the anvils, and the latter may be slid out of the grooves or channels in the supporting-bars 22 for convenience in transporting and storing the apparatus.
